Work Continues to Prepare Artemis I Moon Rocket for Launch (News Release)

Since the Space Launch System (SLS) and Orion arrived back at the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida on July 2, teams extended the access platforms surrounding the rocket and spacecraft to perform repairs and conduct final operations before returning to Launch Complex 39B for the Artemis I mission.

Technicians are working to inspect, fix, and check out equipment associated with a seal on the quick disconnect of the tail service mast umbilical that was identified as the source of a hydrogen leak during the wet dress rehearsal test that ended June 20. Engineers have disconnected the umbilical and are in the process of examining the area where they will replace two seals on the quick disconnect hardware. Working in tandem with those repairs, engineers also completed the last remaining engineering test that is part of the integrated testing operations in the VAB.

Teams also performed additional planned work on aspects of the rocket and spacecraft. Engineers swapped out a computer on the Interim Cryogenic Propulsion Stage called the Inertial Navigation and Control Assembly unit that was used during wet dress rehearsal activities with the one that will be used for flight and will test the unit next week. The newly-installed flight unit includes freshly calibrated inertial navigation sensors and updated software to guide and navigate the upper stage during flight.

Technicians also activated several batteries for the rocket elements, including for the solid rocket boosters and the ICPS. The batteries on the core stage will be activated in the coming weeks, and all the batteries will then be installed. The batteries provide power for the rocket elements during the final portion of the countdown on launch day and through ascent.

Engineers also charged the batteries for the secondary payloads located on the Orion stage adapter and will work to install payloads inside the Orion spacecraft in the coming weeks.
